Distributed Denial-Of-Service: Form of electronic attack involving multiple computers, which send repeated HTTP requests or pings to a server to load it down and render it inaccessible for a period of time. Often used by freedom fighters on the Internet, usually attacking the systems of greedy corporations who want to sacrifice YOUR freedom for their profits.
Man, the RIAA got DDOSed again last Saturday! That's the third time this month! Maybe soon we'll have those kidraping fuckers off the 'net for good!

The Nussy, or the โ€œnose pussyโ€, if you will, was discovered during the corona virus pandemic of 2020. People that had to be tested for Covid-19 had to have their nose swabbed right where the brain connects, which often led to people rolling back their eyes and gagging.

A nose-swab-fetish developed from this, because we, as humans, ruin everything.
โ€œOh fuck yeah, swab my nussyโ€

Sir, please, I went to medical school

Distributed Denial of Service (see DoS). Similar to DoS except in that it's an attack orchestrated from multiple compromised computers onto one target.
1> Dude, can you log onto DalNET IRC?
2> Naw, their servers are being DDoS'ed to hell.
1> Boo. Bunch of script kiddies and lusers I'm willing to bet.

A distributed denial of service is an attack on a web server usually executed by a botnet. The most classic and outdated method is by typing in ping www.urbandictionary.com -t -l 65500 in command prompt to send useless noise to UD's server. In theory, if a large enough botnet did this, it would generate enough noise to clog the bandwidth of the server, denying the webservice offered by said server (preventing normal users from accessing the webpage). However, modern DDOS protections filter out said noise, so various scripts and programs will spam the webserver (www.urbandictionary.com) with requests for the html data, achieving the same goal of clogging the bandwidth. A more refined approach is through DNS reflection, in which a DNS server is tricked into using its large bandwidth to send random data from the service that it offers to the target IP. A bad method used by anonymous is the HOIC or LOIC to attack the server directly, it's a bad choice because each member of the attack must consent to said attack through a fancy graphical interface, so you can't have a botnet do it for you.

A DDOS is highly illegal, so don't try this at home kids
Person 1: Dude I have a 5k botnet now, I'm to DDOS the school now
Person 2: Cool! What type of attack are you gonna use?
Person 1: A DNS reflection

Distributed Denial of Service: the cancer that is (effectively) killing 4chan.
The site is still down due to an ongoing DDoS attack.

Remember kids: DDoS is cruise control for cool.
